Homebridge troubleshooting

Great! Homebridge works very stable and reliable now,
and the graphical UI for controlling the server is also very handy!

Thanks @makerken and @Moors7 for your fantastic guidance. I could not have done it without this great community...

Switching lights ON and OFF with Siri has no secrets for me anymore.
But now I'm trying to explore the communication possibilities in the other direction:

Reading sensors...

From the sample "config.json" file, I kept this "device":

               {
                    "accessory": "ParticleTemperature",
                    "name": "Room Temperature",
                    "deviceid": "222042000b47348882313031999",
                    "type": "SENSOR",
                    "sensorType": "temperature",
                    "key": "temperature",
                    "event_name": "tvalue"
                }

And I read @krvarma's explanation:

Based on this, I tried various combinations of Particle.publish commands, such as:

Particle.publish("tvalue", "key=37",60,PRIVATE);

But the value shown in the Apple HOME App does not change: It shows 20° continuously...
Any experience with this somebody?

Edit: Applying the bold text above, I found the correct syntax for the event to publish:

Particle.publish("tvalue", "temperature=37",60,PRIVATE);

All works now! Thanks @krvarma
